farther on that Tether Idea, If it had and kind of spring loading, It would snap back to the ground in its starting place soon as it reached a distance set as "Far Enough Away"
Again, Just Ideas,, But Nothing Is More True Than "Safety First"
But anyone that hasnt seen how nice it looks watching from a drone has to see it..
I hope someone a bit more savy than I will post one for all to look at..
